Analysis: Intel Core 7 251E vs Intel Core Ultra 7 270HX Plus
Head-to-Head Benchmarks
The database contains a full benchmark suite for the Intel Core Ultra 7 270HX Plus, but no recorded measurements for the Intel Core 7 251E. The comparison therefore rests on the Ultra 7 270HX Plus's absolute scores and its position against nearest rivals, rather than a direct per-test contest between the two processors.
The Core Ultra 7 270HX Plus delivers a Cinebench R23 multi-core score of 41913 and a single-core score of 5917. In Cinebench R20, it records 17603 multi-core and 2485 single-core. Cinebench R15 shows 4224 multi-core and 596 single-core. These results place the chip at the 93rd percentile among all CPUs in the database, with an average benchmark score of 61834.
PassMark results for the Core Ultra 7 270HX Plus show substantial throughput in specialized workloads. The multithread score is 48270, with single-thread at 4764. Data compression reaches 493179, while data encryption scores 37813. Floating point math hits 163567, integer math reaches 122449, and extended instructions score 39283. Prime number finding returns 482, physics simulation records 3843, and random string sorting completes at 60020.
The nearest rivals in the database are all Intel desktop parts. The Core i9-13900KF averages 61841, a delta of 0 percent versus the Ultra 7 270HX Plus. The Core i9-13900K scores 61766, a 0.1 percent gap. The Core i9-13900T averages 61723, 0.2 percent behind. The Intel Xeon 636 scores 61360, a 0.8 percent deficit. The Ultra 7 270HX Plus essentially matches the flagship Core i9-13900K series in average benchmark score despite being a mobile processor with a 55 watt TDP.
Since the Core 7 251E has no benchmark entries, the head-to-head wins are zero for both processors. The available data indicates the Core Ultra 7 270HX Plus is a high-performing part by absolute score and percentile rank, but no direct comparison to the Core 7 251E can be drawn from recorded measurements.

The Verdict
The data shows a clear split in role and measurement status. The Intel Core 7 251E is a desktop processor with 24 cores and 32 threads, a boost clock of 5.60 GHz, and a 65 watt TDP. It has no benchmark scores, so its performance characteristics are unverified in the database. Its percentile rank of 50 suggests it sits near the median of all tracked CPUs, but that figure is not backed by any recorded test.
The Intel Core Ultra 7 270HX Plus is a mobile processor with 20 cores and 20 threads, a boost clock of 5.30 GHz, and a 55 watt TDP. Its benchmark results are extensive and strong. The 93rd percentile and an average score of 61834 place it in the upper tier of processors, statistically indistinguishable from the Core i9-13900K series. For users selecting between these two parts, the Core Ultra 7 270HX Plus is the only one with demonstrated performance, and that performance is top-tier. The Core 7 251E offers more cores and threads on paper, but without measurements, its actual capability cannot be confirmed. The choice depends on whether the user needs the desktop form factor and higher core count of the 251E, or the verified high performance and mobile packaging of the 270HX Plus.
Specification Differences
The two processors differ across several core specification fields. The Core 7 251E has 24 cores and 32 threads, while the Core Ultra 7 270HX Plus has 20 cores and 20 threads. The 251E has a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The 270HX Plus has a base clock of 2.40 GHz and a boost clock of 5.30 GHz. The 251E consumes 65 watts TDP, the 270HX Plus 55 watts.

The 251E supports ECC memory, the 270HX Plus does not. PCIe lanes differ: 16 lanes for the 251E, 20 lanes for the 270HX Plus, both Gen 5. The 251E integrates UHD Graphics 770, the 270HX Plus integrates Arc Xe-LPG Graphics 64EU. The 251E is a desktop part, the 270HX Plus is mobile. Release dates are 2025-01-12 for the 251E and 2026-03-16 for the 270HX Plus.
Architecture Differences
The architecture details show distinct design approaches. The Core 7 251E uses the Bartlett Lake codename, part of the Core 7 generation, built on a 10 nm process at Intel's foundry. The Core Ultra 7 270HX Plus uses the Arrow Lake-HX Refresh codename, part of the Core Ultra Series 2 and Ultra 7 (Arrow Lake-HX) generation, built on a 3 nm process at TSMC. The 270HX Plus has a transistor count of 17,800 million, while the 251E has no recorded transistor count. Die size is 257 mm² for the 251E and 243 mm² for the 270HX Plus.
Cache hierarchies differ markedly. The 251E has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The 270HX Plus has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The 251E's larger L3 pool compensates for its smaller per-core L1 and L2, while the 270HX Plus relies on faster per-core caches and a smaller shared pool. The process node difference is substantial: 10 nm versus 3 nm, which accounts for the 270HX Plus's higher transistor density despite a smaller die. The 270HX Plus also uses an unlocked multiplier, indicating overclocking capability, whereas the 251E is locked. The 251E supports ECC memory and dual memory types, features absent from the 270HX Plus. The 270HX Plus offers 20 PCIe Gen 5 lanes versus 16 on the 251E, supporting more expansion devices. The integrated graphics differ, with the 251E using UHD Graphics 770 and the 270HX Plus using Arc Xe-LPG Graphics 64EU, indicating a newer GPU architecture in the mobile part.
